The almost divorced ‘housewife’ is on the grind and is seeking to find a solid career now that the well has run dry with her ex-NFL hubby Kordell.? She’s been recently seeking bookings for paid appearances and has gotten quite a few paying gigs hosting small time events.

I say all of that to say… that a Florida promoter by the name of Tanika Oliver is claiming that after she paid Porsha half of her booking fee for an appearance, the bubbly ‘housewife’ didn’t even make it to the venue before they shut down.

And wait… Stewart arrived just as they were shutting down inquiring about the balance of her appearance fee.

Porsha Stewart screwed over her fans and essentially stole several thousand dollars, by showing up hours late for a scheduled event … so claims the event organizer who was left in tears.

Tanika Olivier tells TMZ … she hired Stewart to make a 4-hour appearance in Ocoee, Fl. Thursday night.? She wasn’t just an hour late… or 2 hours … or 3 hours.? She showed up 20 minutes before they folded up tent.

According to Olivier … Stewart had a bunch of lame excuses — her flight was delayed … the driver took her to the wrong hotel … and they had to make a stop to change into fresh clothes.

Stewart was paid $2K up front — so claims Olivier — and she had the nerve to demand? the $2K balance. ? Things got ugly and cops were called.

Police told the girls to settle it on their own and Olivier reluctantly cut Porsha a $2K check…? but she tells us she’s decided to stop payment … and she wants the initial 2K back STAT.
